The immune cells discovered under the nose

The scientists of the Weizmann Institute of Science have discovered antibody-producing cells in the bone tissue of the nasal concha and thereby plant hope for the development of more effective nasal vaccines and new treatments for allergies and neurological and autoimmune diseases

Nobel Prize in Medicine 2023 for the pioneers in the field of mRNA who accelerated the vaccines for Corona

Kariko and Weissman immediately realized that their discovery was of enormous significance for the possible use of messenger RNA in medicine. These important findings were published in 2005, 15 years before the outbreak of the Corona epidemic.

Fear of an outbreak of monkeypox

Several cases of the viral disease have been discovered in the United States and Europe and health authorities are preparing to stop its spread. The good news: there is an effective vaccine against it

Development of oral RNA vaccines

Researchers have succeeded in developing a method to deliver RNA in a capsule that can be swallowed, a development that will make it easier to take RNA vaccines
Results of a generally insured study on the effectiveness of the corona vaccine

A thorough study of 1.2 million general insureds proves: the corona vaccine is effective

Final results of the Klalit Research Institute regarding the effectiveness of corona vaccines are published in the medical journal The New England Journal of Medicine: after the first vaccine dose: 57% effectiveness in preventing morbidity and reducing

About the Helsinki Committee - and the dance about the two weddings

In recent days there has been a big uproar regarding the Helsinki Committee, what it determined or did not determine, and what it means for the vaccine. So let's break down the issue, to understand what the Ministry of Health really did wrong, and what

The FDA granted emergency approval for Pfizer and Biotech's corona vaccine

On Friday, the US Food and Drug Administration approved the vaccine for emergency use in people 16 and older. It is now expected that the Ministry of Health will approve the vaccine for emergency use in Israel as well

The connection between the flu vaccine in pregnancy and autism in the offspring has been ruled out

A flu vaccine during pregnancy protects the children and women from illness, but does it also have long-term risks? A decade-long follow-up study refutes this.
